PyPi and release branch source code mismatch

[cemlyn007]

I noticed for Launchpad version 0.5.2 that there is a mismatch between the uploaded PyPi package and the head of the release branch. This is problematic because this line is different in the PyPi package because there is a type mismatch where the expected type should be int but in the uploaded package it is a float due to a division by 1000.
